Application filed November 3, 1927. Serial No. 230,755.

This invention relates to the construction of metal window frames andhas for its general objects to facilitate the manufacture of such windowframes, and the assembling of the same and the window sashes, either inthe factory oron the job, to increase the eliiciency of such Windows inexcluding air, to provide for such disposition of .the pulley chains bywhich the sashes are counter-balanced, that they shall not beconspicuous and shall not be liable to contact with draperies, and tostrengthen such windowframes so they will better resist distortion orbreakage in the rough handling to which they are sometimes subjected intransportation and in erection on the job. These and other purposes arefulfilled b features of construction to be described ereinafter, withreference to the accompanying drawings in which they are illustrated ina convenient practical form and in which:

Figure 1 is a view in elevation of a window frame which embodies theseveral features of the invention, showing one of the jambs, a portionof the head, a portion of the sill,

and portions of the two sashes, the jamb and the sashes being broken outto save space, and portions of the jamb being also broken out and shownin section to illustrate details r of construction.

Figure 2 is a view in sectional elevation on the plane indicated by thebroken line 22 of Figure 1.

Figure 3 is a detail view of a portion of the 5 head of the frame andjamb, seen from above,

with the cap of the head removed, illustrating particularly the relationof the sash pulleys and pulley housing to the head and jamb.

Figure 4 is a detail view in horizontal section on the plane indicatedby the broken line 4.4 of Figure 1. I

Figure 5 is a detail view in elevation of the interposed section of thepulley stile.

Figure 6 is a View of the interposed section of the pulley stile insection on the plane "indicated by the broken line 66 of Figure 5.

Figure 7 is a det ail view in section onthe.

plane indicated by the broken line 7-7 of Figure 2, illustratingparticularly the features of construction involved in the connection ofeach amb to the sill.

Figures 8, 9 and 10 are respectively perspective' views of thereinforcing plates at the top, mid-section and bottom of the jamb, 65 ona smaller scale.

Figures 11, 12 and 13 are respectively perspective views, also on asmaller scale, of the upper, middle and lower portions of the pulleystile, the upper and lower portions being .madeof a single sheet ofmetal, formed to suit the window opening it the wall and to receivewithin it the counter-balance weights, not shown, for the upper andlower sashes as shown clearly in Figure 4. The edge portions of thesheet of metal which for-ms the jamb are bent toward each other andagain 8 toward the back of the jamb, to form jamb members a and (1 theedges being again bent toward each other, in a plane transverse to theplane of the window, to form flanges, as at a and a which are spacedapart throughout the vertical height of the frame. The jamb thus formedis stiffened and strengthened and its edge portions maintained in properspaced relation by three heavy metal reinforcing plats b, 0 and d, shownrespectively inFig-',

' ures 8, 9 and 10, at the top, mid-section and bottom. Each of thesereinforcing plates is a on-the inside, thus maintaining the edgeportions ofthe jamb against spreading and against compression. Thereinforcing plate b is formed at its upper edge with tongues .b, b and bfor connection with the head of i the sill of the frame.

The pulley stile is formedin three sections e, f and g shownrespectively in Figures 11, 12 and 13, each section being formed to fitbetween themembers a and a of the jamb and thereby prevent displacementof the edge portions of the jamb members toward each other. It isdesirable,,in order to maintain exact parallelism of the j amb members,that the opposite edges of each pulley stile portion shall be exactlyparallel, andas a matter of convenience in manufacture such exactparallelism of the edges of the pulley stile members can best beobtained by turnin up the edges as shown at g". Each pulley stile memheris bent to form three projecting vertical sponding flange of the lowersas thus 'conrails e ,.e 6 f f f and g g 9 These rails form, betweenthemselves and with the portions a and a of the jamb, the grooves whichreceive the flanges of the upper and lower sashes z' and is, asindicated clearly in Figure 4;, and the counter-balance"chains,

' one of which is shown at Z in Figures 1 and 2,

Being received in these channels or grooves the counter-balance chainsare less conspicuous than they would be if the pulley stile was notgrooved and they are not liable to contact with draperies. It will beobserved that the vertical ribs'g and g of the lower pulley stile memberare wider than the ribs 6 e", f and f? of the upper and mid members ofthe pulley stile, whereby the channel or groove below the meeting railsof the two sashes is just wide enough to receive freel thecorretributing to the exclusion of air, while the wider channels orgrooves formed by the nar-. rower rails e and e of the upper pulleystile member and the mid-section member are wide 1 enough to receiveproperly the chains Z.

The upper pulley stile member 6 is secured at its lower end to thereinforcing plate 0 by a screw e which engages at its upper edge, as atc the tenon of the middle reinforcing plate 0, and in order that thisupper pulley stile portion 0 may be removed and replaced when necessary,without requiring the removal or replacement of a screw near the head ofthe window frame, this pulley stile member is formed at the upper end ofthe rail c with tongues e and e, as shown in Figure 11, to

enter slots formed in the soflit of the frame head as hereinafterexplained.

The middle pulley stile member I is secured to the middle reinforcingplate 0 by a screw f? which passes through a hole f inthe middle rail)and is threaded into a hole 0 shown in Figure 9, in the tenon of thereinforcing plate 0.

Thelower pulley stile portion 9 is secured to the middle reinforcingplate 0 by a screw g which passes through a hole in the pulley stileportion and is threaded into a hole 0 in the tenon a of the middlereinforcing plate near its lower end. Another screw 9 passes through ahole in the middle rail 9 near its lower end, and is threaded into aholed in the reinforcing plate d,

The lower end of the lower pulley stile member is formed to fit againstthe sill.

To afford the proper contact surface of the sashes to prevent thepassage of air up or down the grooves of the pulley stile and jambaround the flanges of the sashes, at the ends of the meeting rails, theinterposed or middle section 7 of the pulley stile has secured to eachof its rails 7, f and 7, by tongues 71. and h, which respectively enterslots in the pulley stile member, as indicated at f in Figure 12, andlap the end of the pulley stile member, a cap it, which forms a socketfor the reception of rubbing pads h of felt, thus affording a feltbearing for both flanges of each sash and preventing the passage of air.

The soflit m of the frame head m is grooved as at m to receive theflanges across the top of the uper sash z, and within the head,extending from the inner face 'to the outer face, is a heavy metalreinforcing plate n which also forms the base of the housing whichsupports the sash pulleys 0 over which pass the counterbalance chains Z.The tongues 6 b and b of the upper reinforcing plate I; pass up throughslots at m, m and m in the soflit m and through slots at n n and n inthe reinforcing plate nand are bent over upon the reinforcing plate,thereby securing the reinforcing plate n rigidly to the frame head. Atongue (1 of the jamb is also passed up through the slot m and is bentover in a direction opposite to that of the tongue b The jamb is alsoformed with tongues a and a" which are passed up through slots m and min the inwardly turned edge portion of the soflit m and are bent overtoward each other. The j amb' is also formed at its outer face with atongue a which is bent over upon the edge of an extended tongue m of thesoflit. At its inner face the soflit is also formed with an extendedtongue m", the upper edge of which is bent over upon itself as at m andis cut out to form two shoulders m and m. The

inner wall of the jamb is bent over upon the jamb is ri 'dly secured tothe frame head tov prevent ative displacementin a vertical difillrection, and it is also secured to the frame head to prevent relativedisplacement in a horizontal direction.

. The jamb is rigidly secured to the sill p in such manner as to preventrelative displacement in a vertical direction and also to preventrelative displacement in a horizontal direction by means generallysimilar to the means described above for connecting the jamb and theframe head. Theinside depending flange of the vsill is turned back uponitself as at p and the turned up portion is cut out to form shoulders 12and p. The lower edge of the inside wall a of the'jamb is lapped overthe lower edge of the depending flange p of the sill and is formed witha tongue a, which is bent inwardly between the'shoulders p and 7), sothat relative displacement of the jamb and the sill in a horizontaldirection is prevented, while at the same time relative displacement ina vertical direction is also prevented.

To make it possible to attach and detach the counter-balance chain toand from the sash readily, there is secured to the upper corner of thesash bysome suitable means, such as spot welding, a hook q to be engagedby a link of the chain. It thus becomes pos sible to attach or detachthe chain without removing any part of the frame and without removingthe sash from the frame.

The tongues e and e of the upper pulley stile portionare passed upthrough slots or an L-shaped slot at m in the soflit of the head but arenot turned over. Thereby it is possible to slip the upper pulley stileportion into place and secure it in place by the single screw 6 It willbe observed that only four screws are required to hold the entire pulleystile in place.

It will be understood that not all of the herein described features ofthe improvements are necessarily embodied in one-structure but can heused independently of each other if conditions so require and thatvarious modifications in detail of construction and arrangement can bemade without departing from the spirit of the invention except so far assuch detail may be made the subject of some of the following claims.
